This patchset adds elevated refcnt support for page pool
and enable skb's page frag recycling based on page pool
in hns3 drvier.

RFC v2:
1. Split patch 1 to more reviewable one.
2. Repurpose the lower 12 bits of the dma address to store the
   pagecnt_bias as suggested by Alexander.
3. support recycling to pool->alloc for elevated refcnt case
   too.

Yunsheng Lin (5):
  page_pool: keep pp info as long as page pool owns the page
  page_pool: add interface for getting and setting pagecnt_bias
  page_pool: add page recycling support based on elevated refcnt
  page_pool: support page frag API for page pool
  net: hns3: support skb's frag page recycling based on page pool
